Frequently Asked Questions: Ardo AL06
FAQ TREEWhat does error code AL06 mean on a Ardo appliance?
Ardo error code AL06 indicates: Ardo DWA / DW60 Electronic Integrated & Freestanding Dishwasher: Diagnostic fault code AL06 registered by the microcomputer controller. Water temperature NTC thermistor sensor probe open circuit or out of tolerance.
What is the root cause of Ardo error code AL06?
The primary root cause for Ardo code AL06 is: On Ardo appliances engineered with tachometric circulation wash pump, 2040W flow-through heater, Bitron overflow float microswitch, and 10 kΩ NTC turbidity sensor: thermistor probe internal wire disconnected or terminal contacts corroded with green oxide Metrological tolerance verification: sump NTC resistance nominal 10.0 kΩ at 25°C, 2.5 kΩ at 60°C; fault if > 150 kΩ..
How do I fix or resolve Ardo error code AL06?
To resolve error code AL06: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: unplug sensor harness from sump housing and measure resistance across pins at 25°C ambient. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Switch on power. Press and hold the Program Selection key for 5 seconds until the cycle progress LEDs flash simultaneously and the acoustic tone beeps three times. Turn off machine at master power button, wait 15 seconds, and restart standard cycle.
Is it safe to clear Ardo error code AL06 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ardo code AL06 persists, the physical component causing On Ardo appliances engineered with tachometric circulation wash pump, 2040W flow-through heater, Bitron overflow float microswitch, and 10 kΩ NTC turbidity sensor: thermistor probe internal wire disconnected or terminal contacts corroded with green oxide Metrological tolerance verification: sump NTC resistance nominal 10.0 kΩ at 25°C, 2.5 kΩ at 60°C; fault if > 150 kΩ. must be inspected or replaced.
How do I test electrical resistance for Ardo code AL06 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..
What safety protocol must be followed before servicing Ardo code AL06?
Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
